The paper analyzed sedimentary characteristics and depositional environment in t1f3 this region firstly, and on the grounds of establishing logical deposit pattern gave emphasis to make a study of distributing laws and spreading traits of the oolitic beach. because diagenesis is a vitally dominating factor that influenced oolitic beach reservoir nature in the region, the master diagenetic events of the reservoir in the lengthy geological history, as well as the influence to the pore abundance, was made a study of. the diagenetic stages and sequences were divided and the pore evolve pattern was established in the paper
本論文首先分析了研究區飛三段的沉積特徵與沉積環境，在合理建立沉積相模式的基礎上重點研究了鮞粒灘（壩）的分佈規律和空間展布特點；成巖作用是影響本區鮞灘儲集性至關重要的控制因素，論文詳細研究了儲層在漫長地質歷史過程中所經歷的主要成巖事件及其對孔隙發育的影響，劃分了成巖階段與成巖演化次序，建立了孔隙演化模式並以建南構造為例進行了成巖相展布研究的嘗試；最後還在鮞灘儲層基本特徵研究的基礎上對飛三段儲層進行綜合評價與預測。 -
